TUB FOR ELECTRIC BA THS.

SPECIFICATION forming part of Letters Pa.tent No. 755,830, dated March29, 1904.

Application filed November 24, 1903. Serial No. 182,515. (No model.)

To all whom it may concern.-

Be it known that I, J OSEF ZWIEBEL, proprietor of a sanatoryestablishment, a subject of the King of Bavaria, residing at Neu-Ulm,Bavaria, German Empire, have invented certain new and usefulImprovements in Tubs for Electric Baths, of which the following is aspecification.

My present invention relates to an electricbath tub whereby the personbathing is enabled to connect or disconnect the electrodes withoutleaving the bath.

The invention is illustrated in the accompanying drawings.

Figure 1 is a top view of the tub. Fig. 2 is a detail view showing thesliding arrangement.

On the upper edge of the tub a rods d, made of conductive material, onwhich the electrodes are strung, are provided on the sides 5,respectively, of foot ends 0 of the tub. These rods may also be placedin recesses of the tub edge to enable a sideward slide of theelectrodes. These rods cl are connected with the poles of the battery,so that the electric current may pass through the body of the personbathing. The electrodes g on the rods are preferably made of coal andhave metal hooks at. the end. The current flows through the metal rodsto the electrodes connected to them and from these through the bath.

In order to enable the person bathing to disconnect any of theelectrodes in an easy way, the rods 61, which carry the electrodes 9,are provided with non-conductive material f, according to the invention,so that conductive and non-conductive parts are partly on the rods ofthe electrodes. In order to have a smooth surface of the rods, the rodscl are suitably provided with corresponding recesses e, which are filledor lined with non-conducthe rods to the electrodes.

tive material f. Any kind of non-conductive,

material may be usedrubber hose, hard rubber, caoutchouc, &c. Thecurrent can therefore flow along the conducting parts of Beneath theisolations f the current, however, flows directly through the rod to thenext electrode hung up on the conducting part. In case the personbathing wants to disconnect or connect one or more electrodes this canbe done by sliding them on the isolations, respectively, on theconducting parts.

Theelectric shock received by touching the electrodes is not sensitive.This can be avoided by covering the electrodes with suitable wrappingsor with isolation material.

In order to have the current-circuit through the body of. the personbathing from head to foot, electrodes are also fixed on electroderods atthe foot ends 0 of the tub. These electrodes may also be supplied withisolations.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is

An electric-bath tub with rods of conductive material on the sides forstringing up the electrodes, the rods carrying the electrodes providedat certain distance with isolation material, as hard rubber, &c.,suitably fitted in recesses for the purpose of cutting ofl the difierentelectrodes from the current by sliding on isolating parts substantiallyas and for the purpose set forth.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.

JosEE ZWIEBEL.
